Multipartite entanglement features of primordial non-gaussianities

Alessio Belfiglio, Roberto Franzosi, Orlando Luongo

We discuss some entanglement features associated with cubic non-Gaussian perturbations in single-field inflationary scenarios. We adopt standard momentum-space techniques to show h…

Geometric multipartite entanglement from gravitational particle production

Alessio Belfiglio, Roberto Franzosi, Orlando Luongo

We explore novel generation of genuine multipartite entanglement within gravitational particle production processes during inflationary stages. To this end, we focus on perturbativ…

Quantum entanglement in cosmology

Alessio Belfiglio, Orlando Luongo, Stefano Mancini

We discuss recent progress in the study of entanglement within cosmological frameworks, focusing on both momentum and position-space approaches and also reviewing the possibility t…

Gravitational dark matter production from fermionic spectator fields during inflation

Alessio Belfiglio, Orlando Luongo

We investigate the gravitational particle production from vacuum for a minimally coupled fermionic spectator field during a single-field inflationary phase. We observe that metric…

Entanglement entropy evolution during gravitational collapse

Alessio Belfiglio, Orlando Luongo, Stefano Mancini +1

We investigate the dynamics of the ground state entanglement entropy for a discretized scalar field propagating within the Oppenheimer-Snyder collapse metric. Starting from a well-…
